Description
Inclusion Criteria:
- Age ≥18 years;
- Diagnosis of primary APS, meet 2006 Sydney classification criteria or continuously positive for antiphospholipid antibodies within the first 12 months of inclusion (tested at least every 12 weeks), classified as high-risk antiphospholipid antibody spectrum based on the risk of antibody levels, in order to meet at least one of the following conditions: 1. Positive lupus anticoagulant (LAC) (tested according to ISTH guidelines); 2. Two or three types of aPL positivity (lupus anticoagulant, anticardiolipin antibody, and anti-β2 any two or all three types of glycoprotein I antibodies; 3. Or persistent high titer aPL;
- There are no other autoimmune diseases occurring simultaneously;
- According to EULAR recommendations for antiphospholipid syndrome, a stable APS treatment regimen should be adopted;
- Female patients who are not pregnant, breastfeeding, have no fertility potential, or have not undergone contraception.
Exclusion Criteria:
- Patients with a history of malignant tumor in the past 5 years, except for basal cell carcinoma or squamous cell carcinoma of skin or cervical carcinoma in situ treated locally, and there is no evidence of metastasis within 3 years;

- HIV test is historically positive or HIV screening is positive;
- Hepatitis status;
- Patients with a history of allergic reaction caused by injection of contrast agent, human or mouse protein or monoclonal antibody;
- Patients with other abnormal laboratory values with clinical significance;
- If women with reproductive potential (WCBP) are included, please refer to the following special instructions;
- Patients with concurrent major medical or mental illnesss;
- Patients with diseases of liver, kidney, heart and other important organs,blood and Endocrine system;
- Patients who have been vaccinated with live vaccine in the last month;
- Patients who have participated in any clinical trial within 28 days before the initial screening and/or within 5 times of the half-life of the study compound (whichever is longer);
